Yep, there will usually be opportunities for arbitrage for active traders if there are too many passive investors. I suspect there will be some sort of equilibrium between active and passive at some point.
The thing is that I'd rather be doing other things with my time, so I'm a passive investing kind of guy. Imagine getting the market return for doing nearly nothing for dirt cheap. That's a high growth rate to level of effort ratio!
